That old saying that a chain is only as strong as its weakest link comes to mind. The weak link in todays rigs (ALF, Pierce, et al) is computers...there are a huge number of computers and problems arise when they begin "saying" things that conflict with one another. As an example, I worked on a rig from one of the big three that when in pump gear would idle up and down constantly, no matter if you had water flowing or not. Turns out, the transmission computer was saying one thing while the computer in the Detroit Fire Commander was saying the opposite, thus causing the oscillations. All three computers were replaced and no more problems, it had nothing to do with the logo on the grill.
